Keyword Density Checker

How to use the keyword density checker

1. Paste your article, product page or draft into Content to analyze. The results update as you type.
2. Under Phrase length, choose 1 word, 2 words or 3 words to see single keywords or longer expressions such as “coffee beans” or “cold brew coffee”.
3. Keep Ignore stop words checked to hide words like “the”, “of”, “and” or « de », « la », « et », which dominate every text but say nothing about its topic.
4. Optionally type a Focus keyword to see exactly how many times it appears and its density.
5. Use Show to list the Top 10, Top 20, Top 50 or All phrases, and Export CSV to open the full list in a spreadsheet.

Everything runs in your browser: the text you paste is never uploaded.

How keyword density is calculated

The tool uses the usual definition:

Density = occurrences × words in the phrase ÷ total words × 100

A two-word phrase that appears 3 times in a 300-word text covers 6 of those words, so its density is 6 ÷ 300 × 100 = 2 %. Multiplying by the phrase length makes single words and longer phrases comparable: the figure is the share of the text taken up by that phrase.

Total words always counts every word, stop words included, whichever options you pick. Unique words is the number of different words, and Distinct phrases the number of different phrases in the table.

How words and phrases are counted

• Matching ignores case: “SEO”, “Seo” and “seo” are the same keyword.
• A word is a run of letters or digits in any alphabet. Hyphenated words (“e-mail”, “peut-être”) and English contractions (“don’t”) stay whole. Straight and curly apostrophes are treated the same way.
• French elisions are removed so that “l’été” and “été” count together; the same goes for d’, qu’, n’, s’, c’ and similar forms.
• Phrases never run across a sentence end, a line break, a comma or a dash, so “roasted. Fresh” is not counted as a phrase.
• Numbers on their own are skipped, since “2026” or “42” are rarely what you want to measure.
• With Ignore stop words, a 2- or 3-word phrase is skipped when it starts or ends with a stop word (“of the”, “the best”), but a stop word in the middle is kept, so “crème de marron” still appears. The built-in list covers common English and French function words.

What to do with the results

Keyword density is not a ranking target. Search engines have not used a fixed percentage for many years, and Google has said repeatedly that there is no ideal density. Repeating a phrase to reach a number makes a text harder to read and can be treated as keyword stuffing.

The numbers are useful for other things: spotting a word you repeat far more than you meant to, checking that the main topic of a page is actually the most frequent subject, comparing your draft with the vocabulary of pages that rank well, or finding related 2- and 3-word phrases worth covering in their own section. Synonyms and related terms help readers and search engines understand a topic better than repetition of one exact phrase.
